CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 61/736,603 filed on Dec. 13, 2012, entitled “Door Sculptor.” The above identified patent application is herein incorporated by reference in its entirety to provide continuity of disclosure.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to an exercise devices. More specifically the invention relates to a pulley system configured for removable attachment on a doorway, and wherein the system is further adapted for supporting weights.

The exercise of weight lifting has origins that have been traced back to the beginning of recorded history and remains one of the most popular forms of exercises today. The act of lifting weights is a form of strength training that strengthens the muscles of the body and further serves to increase the overall health of a user's body. The exercise comprises lifting or moving an object having a certain mass against the force of gravity. Repeated acts of lifting facilitate the gradual increase in the strength and mass of the muscles that perform the lifting of the weights.

Weight lifting can improve the overall health of the user, increase muscle mass, and promote weight loss. These body changes are particularly useful for those playing sports as well as those who typically live a sedentary life. To make exercise more convenient for those who may not have a lot of free time in their day, there are a variety of exercise devices that are available for use in a home setting. These devices include stationary equipment adapted for supporting a person, barbells and dumbbells moved by a user, and simple machine systems attached to a weight that is lifted by a user. These simple machines comprise a pulley, lever, a wheel, or an incline that alter the force of the weights a user must lift.

Pulley systems are often favored among the plurality of available exercise machine systems because they enable a variety of exercise activities to be performed on a single setup. Furthermore, pulley systems enable quick changes between weight amounts and allow a single person to perform activities, often without requiring the assistance of a spotter. The setbacks of choosing a pulley system exercise machine are that they often are stand-alone systems that occupy a large section of a room and they are not easily movable once situated.

There are several devices that attempt to provide pulley system exercise machines that do not require much space or setup. These pulley systems are door mounted or ceiling mounted to save interior room space. The drawbacks of these systems are that they are often either permanently attached to a doorway, or are attachable by a clip to a permanently installed frame. Because these devices are not supported on the doorway by their own forces, transporting the pulley systems from one location to another involves complex disassembly and reassembly in another doorway. Reinstallation typically requires securing the system with screws or similar fastening devices. What is needed is a pulley system exercise machine that is supported by its own weight when installed in a doorway. Furthermore, a pulley system is desired that is portable and comprises an attachment for the addition of a plurality of weights.

The present invention relates to pulley system exercise machine assembly that is removable from a doorway and occupies a minimal amount of space. The exercise assembly includes a hanging pulley with a cable running through the pulley that connects a weight on one end with a handle on its opposite end. The assembly does not require any permanent connections such as screws inserted into the doorway. The installed assembly is supported within a conventional doorway by its own weight. The exercise assembly spans the width of the doorway and enables a user to completely remove the assembly after use, thus allowing the doorway to maintain a clean look when the system is not installed. The assembly has an attachment for addition of a plurality of weights to provide sufficient resistance for those of all fitness levels. In this way, the present invention provides a novel hanging pulley assembly that allows all users to exercise in their home without the need to purchase large equipment or systems that require mechanical supports that could potentially damage the frame of a doorway.

2. Description of the Prior Art

Devices have been disclosed in the prior art that relate to pulley assembly exercise devices. These include devices that have been patented and published in patent application publications. These devices generally relate to pulley assemblies that occupy a large area of a room or systems that are permanently attached to a doorway. The following is a list of devices deemed most relevant to the present disclosure, which are herein described for the purposes of highlighting and differentiating the unique aspects of the present invention, and further highlighting the drawbacks existing in the prior art.

Specifically U.S. Pat. No. 4,109,907 to Zito describes a home weight lifting exercise device having clips for engagement over an upper edge of a door. When the door is closed, the clips are between the door and a doorframe, the clips are held in place by the closure of the door on the doorframe. A pulley system is attached to the clips and provides a connection between a user and weighted sandbags adapted for strength training. While the exercise device of Zito is similar in nature and relevant to the present invention, it differs in that it is supported on the door instead of being self-supporting.

U.S. Pat. No. 4,428,578 to Kirkpatrick teaches an exercise device that is connected to the bottom edge of a door when the door is closed. The device includes a clamp that attaches to the bottom of the closed door, a stretchable cord, and a handle that connects to the cord. To use the device, the user attaches the clamp to the bottom of a door and closes the door to provide a secure connection therein, then to begin the exercise, the user pulls on the handles against the resistance of the cord. Although the exercise device of Kirkpatrick is similar in nature and relevant to the present invention, it differs in that it is supported by a door bottom rather than being self-supporting like the present invention, and further fails to offer a pulley system connected to weights.

U.S. Pat. No. 5,050,869 to Frate teaches a portable exercise machine that can be mounted to a side of a door frame. The exercise machine attaches to the side of the doorframe by a pair of fads that tighten to clamp onto the frame. The machine includes a pair of upper and lower pads, a pad adjusting means, a series of pulleys, a cable attached to the pulleys, and a handle. While the portable exercise machine of Frate is similar in nature and relevant to the present invention, it differs in that it doesn't span the width of the doorway.

U.S. Pat. No. 5,820,529 to Weintraub discloses a dual operational exercise resistance device that attaches to a supporting structure, such as a freestanding platform base, a wall, or a door. The resistance of the device is easily adjustable and the device comprises a base unit and a pulley attached to the base unit. When a cable on the pulley is pulled, the lever arm pivots. As the lever arm pivots, the biasing means stretches and provides resistance to the user. Although the exercise device of Weintraub is similar in nature and relevant to the present invention, it differs in that it fails to provide its own support, and further differs in that it is not easily portable.

U.S. Pat. No. 7,621,847 to Lamle teaches a doorway mounted exercise device having upper and lower bars bridging the doorway that support pulleys. The upper bar is collapsible for removal to enable a person to walk through the doorway, and the lower bridging bar is hinged to allow swinging against the door so as to not obstruct the doorway when not in use. Although the doorway mounted exercise device of Lamle is similar in nature and relevant to the present invention, it differs in that it fails to provide an exercise device that is supported without permanent attachments to the door frame, and further differs in that it is not easily removable.

U.S. Patent Publication No. 2005/0250619 to Daikeler teaches a doorway mounted exercise apparatus that is held in place using the user's own body weight. The exercise apparatus comprises first and second L-shaped members, connecting members, and gripping members. When installed in a doorway, the device clamps against either side of the door and the user can hold the gripping bars and hang therefrom to perform pull-ups. The user's own weight serves to hold the exercise apparatus securely in place in the doorway. While the exercise apparatus of Daikeler is similar in nature and relevant to the present invention, it differs in that it fails to offer a pulley system for attachment to weights.

The present invention relates to a new and improved on-door exercise system. The device spans the width of a doorway, occupies a minimal amount of space when compared to stand-alone systems, and is easily and completely removable from the doorway. The exercise system includes a hanging pulley system including a series of three pulley wheels with a cable running through that connect a weight on one end with a handle on its opposite end. The system comprises an attachment for holding a plurality of weights that provide a range of resistance levels to suit the needs of users with a variety of fitness levels. Additionally, the system does not require any permanent connections such as screws inserted into the doorway, and the system is supported on a conventional doorway under its own weight. Furthermore, the removable exercise system enables a user to exercise at home while maintaining an unobstructed doorway when the system is not in use.

In view of the drawbacks of the prior art devices, it is shown that the prior art has several known setbacks and that the present invention is substantially divergent in design elements from the prior art and subsequently it is clear that there is a need in the art for an improvement to existing in-doorway exercise devices. In this regard the instant invention substantially fulfills these needs.

Reference is made herein to the attached drawings. Like reference numerals are used throughout the drawings to depict like or similar elements of the in-door exercise assembly of the present invention. For the purposes of presenting a brief and clear description of the present invention, the preferred embodiment will be discussed as used for enabling the use of a pulley exercise assembly in a home setting. The figures are intended for representative purposes only and should not be considered to be limiting in any respect.

Referring now to FIG. 1, there is shown the preferred embodiment of the in-door exercise assembly of the present invention. The in-door assembly 5 is designed to enable a user to exercise with a pulley system in a home setting and includes a main body frame 10 with an attached pulley system 40.

The main body frame 10 comprises a pair of arcuate members 15, 16, and three steel cross members 20, 25, and 26 that connect the left 15 and right 16 arcuate members together. Each of the arcuate members and cross members are secured together by bolts 33, welding, or by fastened by other suitable means in the art. The arcuate members curve and may form a bend such that they are substantially L-shaped.

The cross members 25 and 26 support the pulley system 40, and are secured opposite cross member 20, which is rectangularly shaped and is configured to lie flat against a door frame. The opposing arcuate members 15 and 16, are attached at their proximal ends by the rectangularly shaped cross member 20, and at an opposing end by cross members 25 and 26. The cross members 25 and 26 are securely attached to the distal ends of the arcuate members 15 and 16, however the cross members 25 and 26 lie on the lower and upper surfaces of the arcuate members respectively. The securement of the cross members 25 and 26 on differing surfaces of the arcuate members aids in distributing the forces that accompany the use of the exercise device 5.

The pulley system comprises a pulley body frame 40 including apertures 35, 36, for the reception of two of the cross members 25 and 26 of the main body frame 10 and further includes a series of three pulley wheels 45, 46, and 47 connected to the pulley body frame 40 by a plurality of apertures 48 and bolts 49 about which the pulleys 45, 46, and 47 rotate. The set of three pulleys 45, 46, and 47 are located at the proximal, middle, and distal ends of the pulley frame 40. These pulleys facilitate the distribution of the forces applied to the assembly 5 when the assembly 5 is connected to a plurality of weights during exercise movements.

To assemble the preferred embodiment of the in-door pulley assembly 5 the pulley system 40 is secured to the main body frame 10. First the rectangular shaped crossing member 20 including a door protecting padding 21, is secured at its proximal and distal ends to the left 15 and right 16 arcuate members by bolts 33 or by other suitable fastening means of the art. Separately the pulley system 40 is secured to the cross bars 25, 26. The cross bars 25 and 26 are inserted through apertures 35, 36 respectively, that are located on either side of the pulley system 40. Next the crossbars 25 and 26 that are connected to the pulley system 40 are secured to the arcuate members 15, 16 by bolts 33 similar to that which secure the crossing member 20 to the arcuate members 15 and 16.

Referring now to FIG. 2, once the frame 10 is secured to the pulley system 40, the pulley cable 50 can be attached to the system 5. The cable 50 can be comprised of wire ropes, nylon coated wire ropes, braided cables, chain links, or other suitable cable that fits around the pulley system 40 and supports the forces of the attached weights 80. To install the cable 50, one end of the cable 50 is placed around the top of a first pulley 45 and pulled until a sufficient length of cable 50 reaches the underside of a second pulley 46. The cable 50 is pulled around the underside of the second pulley 46 around the pulley 46 until the cable 50 reaches an upper portion of the third pulley 47. Finally, the cable 50 is pulled along the upper side of the third pulley 47 and down along the pulley 47 to enable the series of pulleys rotate with the movement of the cable 50.

To secure the assembly 5 to a doorway 85, first the crossbar 20 and the pair of arcuate members 15 and 16 are inserted through the doorway at a length that does not permit the crossbars 25 and 26 to pass through the door entrance. The crossbar 20 is placed on an upper portion of the doorway 85 and the rest of the assembly 5 is rotated downward until the pair of rubber paddings 30 and 31 of the crossbar 25 contact the sides of the doorway 85. The placement of the doorframe 85 positioned between the crossbars 20 and 25 enables the assembly 5 to remain attached to the doorway 85 under its own weight and orientation of the crossbars 20 and 25. Furthermore, placement of the rubber paddings 30 and 31 on the ends of the crossbar 25 and the padding 21 of the first crossbar 20 aid in providing friction against the doorway 85 to prevent any slippage of the assembly 5. Furthermore, the paddings 21, 30, 31 additionally aid to protect the doorway 85 against any damage as a result of the forces applied to the assembly 5 when a user is performing an exercise routine.

The pulley cable 50 includes an attachment clip 55 for connection to a variety of gripping attachments 60 that a user can grasp to perform their exercises. The gripping attachments 60 can be one or more of abdominal straps, ankle cuffs and straps, curl bars, traditional grips, lat bars, seated row handles, straight bars, and triceps ropes, or other suitable attachments known in the art.

Referring now to FIG. 3, there are shown a plurality of weights attached to a weight holder 70. The weight holder 70 includes central stem 75 and a large base 76. The selected amount of weights is slid over or onto the weight holder 70 until the proper resistance is achieved; wherein the weights can be weighted plates 80. The stem 75 of the weight holder 70 is adapted to receive a plurality of weights 80, and the base 76 is adapted to hold the weights 80. Although the base is shown to be circular, it is within the scope of the present invention to include a base section having other shapes including but not limited to shapes such as oval, square, rectangular and triangular.

Referring to FIGS. 4A and 4B, there are shown a perspective views of the preferred embodiment showing the connection to a set of weights 80 in the doorway 85, and a view of the in-door assembly 5 of the present invention while in use, respectively. The assembly 5 comprises a main frame 10 including a set of three crossbars 20, 25, and 26, connected by left 15 and right 16 arcuate bars. Furthermore, the main frame 10 is connected to a pulley system 40 having a set of three pulley wheels 45, 46, and 47 that hold a pulley cable 50. The cable connects the user to weights 80 that reside on a weight holder 70 having a central stem 75 and a base 76 having cutouts 78 thereon, with an opposing end connected to a gripping portion 60 that the user grasps to apply an opposing force to the weights 80. When the user applies a force to the gripping portion 60, the cable 50 moves along the pulleys 45, 46 and 47 of the pulley system 40. The cable 50 movement initiates pulley 45, 46, 47 rotation and facilitates the lifting of the weights 80 off the ground when a force is applied to the gripping section 60. The gripping portions 60 can be one or more of a plurality of attachments including that of abdominal straps, ankle cuffs and straps, curl bars, traditional grips, lat bars, seated row handles, straight bars, and triceps ropes. Thus, the device is capable of being used in a variety of positions that best fit the type of attachment used. Furthermore, the assembly can be used in a sitting, standing, kneeling or other similar positions to exercise.

To remove the assembly 5 from the doorway 85, first the weight holder 70 and the gripping 60 portions are separated from the clips 55 of the ends of the pulley cable 50. Next the pulley cable 50 is pulled from one of the ends and removed from the pulley system 40. Finally the assembly 5 is lifted and rotated forward so that the crossbar 20 is moved away from the doorway 85 and the assembly is separated from the doorway 85.

The present invention is designed for users who wish to exercise at home without requiring the use of large exercise equipment such as those commonly seen in gyms. The present invention is further designed for those who wish to have an exercise assembly that is installable on a doorway 85 and supported by its own weight. The present invention spans the width between sides of a doorway and is easily removable therefrom. The in-door exercise system 5 of the present invention includes a main body section 10 securable to a doorway 85, and a hanging pulley system 40 connected to the main body section 10. The pulley 50 is inserted through the pulley system 40 by being pulled over a first pulley 45, under a second pulley 46, and over the third pulley 47. The opposing ends of the pulley cord 50 are then connected to a gripping handle 60 at one end and to a plurality of weights 80 at the opposite end that apply a resistive force for the user.

Furthermore, the present invention is easily installed and removable on a doorway, and comprises no permanent fixtures that have the potential to damage a doorway 85. The assembly 5 includes a clip 55 for the attachment of a variety of gripping portions 60 for the manipulation of the resistive weights 80. Furthermore, the assembly can be used in a variety of positions including sitting and standing that enable a user to perform a wide range of exercises with the in-door assembly 5 of the present invention. After use, the exercise assembly 5 completely removes from the doorway 85, enabling a user to have an unobstructed doorway when not in use. In this way, the present invention provides an assembly 5 for performing a multitude of exercises in a home setting without needing equipment that requires a large amount of space or permanent fixtures.
